OT: Suffocation educates us on History

I caught a glimpse of this a few nights ago and thought "was that slayer?".
Then I thought that it's probably no one and was just something the channel threw together. No idea it was Suffocation.

What song and album is it from?
 
I think it's cool that neither part was too full of themselves to be invovled with the other. Suffocation are a great band. I love the new CD.
